<pre>i feel ridiculous asking for a null-modem adaptor...
and certainly one can be made with a bit of soldering on a regular cable (which we have extras of)
but if anyone has a null-modem adaptor laying around, i think we need it for the robot. A DE-9 to DE-9 (male to female) would be ideal, although a DB-25 one would work too. Even if it goes from 25 to 9 pins that would be fine. We have lots of regular serial cables.
This is to hook the 3d-printing desktop computer up to the robot, so we can make it do more stuff. I am not sure a null-modem adaptor is needed, but it doesn't seem to say anything at all without one so i'm guessing that's the problem. Normally a disk drive (which we have) plugs into this port on the robot, so to connect the robot to a computer would suggest DTE-DTE which would require a null-modem adaptor.
